What is the
difference between Beta hCG and Clinical Pregnancy Status?
The earliest sign of a pregnancy is the beta hCG hormone, which can
be found in blood work twelve to fourteen days after ovulation.
Clinical pregnancy is diagnosed when a fetal heart beat can be seen
on ultrasound, usually around six to eight weeks from the last
menstrual period (four to six weeks after ovulation).
What is CARTR?
Since 2001, under the
leadership of the Canadian Fertility and Andrology Society and the
IVF Medical Directors of Canada, all in vitro fertilization (IVF)
centres in Canada have voluntarily participated in the collection of
nationwide data on the results of IVF treatment cycles (including
intracytoplasmic sperm injection
[ISCI] cycles). This data is
tabulated in the
Canadian Assisted Reproductive Therapies Register (CARTR),
and reported annually, by clinic and by nationwide averages (see
www.cfas.ca for further
details). In the most recent report, the CFAS confirmed that the
rates of pregnancy and live birth in the country's fertility clinics
are on par with other national registries, including the United
States. The complication rates remain low.
Starting in January 2013, CARTR will be merging with
& Network (BORN) Ontario, the Ontario perinatal registry.
will enable improvements in CARTR data
collection, analysis, and reporting. In addition, for infants born
in Ontario, it will allow more detailed and extended follow-up of
the health of mothers and infants both before and after birth.
